About One Fact Inc
one fact in one place, One Fact everywhere
One Fact offers professional services, consulting, training and support around systems modeling, embedded control and for the BridgePoint xtUML modeling tool.
We specialize in eXecutable Translatable UML (xtUML). We help customers improve their application development process by leveraging the benefits open-source xtUML provides. This means your product has a faster time to market, is more robust, and has reusable components for future projects.
Our expertise spans all three areas of xtUML: application modeling, model execution, and translation to implementation code.
Of course, since our team built BridgePoint upon the Eclipse framework, we have extensive experience using Java to create and enhance application software. We also have many years of experience in embedded programming covering a variety of industries and applications.
Additionally we offer consulting around UML standards, modeling techniques, model review, Eclipse, Java, C/C++, embedded software, legacy applications, configuration management, issue tracking, engineering processes, tools integration, model-driven workflows and more.
We can customize and extend the open-source xtUML tools to meet your needs.
Training & Consulting
Need advice and training about xtUML modeling or improving development process, we can help.
If you have any questions please feel free to contact us.

…or Generalization and Specialization. In a modeled system, it is often important to categorize the entities in the system. Shown below a sedan and a sports car are both types of car each having a specialization. A convertible is a specialization of sports car.
Eclipse Oxygen You can breathe easier; BridgePoint is now running on Eclipse Oxygen. We skipped Neon, and it is too soon for Photon. Oxygen keeps the xtUML editor, Verifier and model compilers on a platform that is mature yet fresh. Download a nightly build.
LEGO robots are toys, fun toys. But they also are widely used in the engineering community for research and education. The platform is relatively sophisticated and quite powerful. The LEGO MindStorms EV3 programmable brick is built from a TI Sitara AM1808 (ARM926EJ-S core) running @300 MHz. There are 64MB of RAM, 16MB of onboard flash

Easy Chair Conference season is coming. MODELS 2018 is in Copenhagen in October. xtUML will be represented in the EXE and MDETools workshops. Of course, xtUML Days will be Monday and Tuesday. Most conferences these days use EasyChair to submit and evaluate papers and presentations. We are a fan; it is a great system. See

MC-3020 has a new feature called State Save. A mechanism to capture the present state of all state machine instances is provided through the State Save feature. Once triggered, the current state of each running instance state machine is written to a buffer. Outstanding events from the event queues are also written to the buffer.

xtUML Days 2018 is co-located with MODELS in Copenhagen, Denmark in October. MODELS is increasing its focus on Industrial Modeling while maintaining the academic and research strength of the conference. The graphic highlights the different industrial opportunities at MODELS this year.
We like the BeagleBone Black development board. It is small, fast and runs full Debian Linux. We jacked it in to our network, ssh’d to it and started development. gcc is on-board, so we can edit our source with vim and compile on-board. Anything missing is just an ‘apt install’ command away. BridgePoint xtUML models translated

Simulated Time in MC-3020 implements a form of discrete event simulation. In simulated time mode, no external clock is read. The application runs as fast as the architecture allows. The time base is derived from timers used to cause functional delays in the production application. SystemC and Verifier both support modes where time is “simulated”.

Congratulations to Levi Starrett upon his promotion to Chief Software Architect. Levi is responsible for the structure and technology of BridgePoint. And will… Research and choose technologies for implementation (such as Java, EMF, Eclipse, Xtext, Python, M2M). Define and maintain interfaces between modules in the tooling. Freshen the technology in a manner that is “Incremental,

The previous post posed Einstein’s Riddle and supplied a class diagram to abstract the information. Here is the solution in BridgePoint running Verifier. In the Session Explorer to the left, you can see the instances of ‘owner’ and the links to the correct instances of each of ‘house’, ‘pet’, ‘tobacco’ and ‘beverage’. Here is a
